Towards a Usage Control based Video Surveillance Framework

The increasing need for physical security in critical environment has led to a widespread of video surveillance systems. Effective video surveillance systems should be able to detect the presence of unauthorized people in the monitored environments while preserving the privacy of authorized ones. To this aim, our paper proposes the adoption of the usage control model in the video surveillance scenario to enforce security policies that continuously control whether a person holds the right to stay in a give space (e.g., a room) from the moment when this person enters that space. In some scenarios, a person is allowed to stay in the room only under some circumstances, which are described by the usage control policy. When the policy is violated an action is taken, e.g., the video camera placed in the room enables the registration. This paper presents the architecture of the proposed framework, provides an example of usage control policy in a real scenario, and describes the main details of our prototype implementation.
